About 15 years ago I had a head injury. I never had it checked out. Now my lump has swelled up three times the normal size, I'm having nausea and dizziness, very fatigued,and headache's. The bump isn't very sore to touch, but icing it is painful. It's been going on for about a month now. My Drs have not been very helpful. One said it was allergies. (I don't have any) does anyone have an ideas of what it could be!??
